"[The marriage] made for a very nice story, but it eliminated an important part of the Superman mythos: the struggle between the two halves of Superman — his publicly known face, admired by millions, and his human side, meek and emotionally vulnerable," Busiek said. "There's some value to be had in exploring their married life, but I'm not sure that's something that couldn't be gotten from exploring some other hero's married life, and I don't think it outweighs the value of that great dichotomy that was always at the heart of Superman, the idea of Superman as the symbol of adulthood and power, and Clark as the inner, less-respected adolescent self-image. That made Superman appeal to younger readers for decades, and made a very strong character engine.
"Writing them as a married couple is fun, because I like that romantic, supportive banter," Busiek added, "but it does soften the concept."
